Liphook Equine Hospital (LEH) would like to alert colleagues that they have diagnosed five cases of atypical myopathy (myoblobinuria/myoglobinaemia) in the past seven days. LEH are also aware of a further four cases attended by veterinarians which have died in the Hampshire/Sussex/Surrey area. They have advised that co-grazing horses should be removed from affected pastures.
Cases have been treated with analgesics (non-steroidal anti-inflammatory drugs, opioids, lidocaine), parenteral nutrition, isotonic intravenous fluids, nasogastric laxatives and supportive nursing care, multivitamin supplementation and electrolyte optimisation. LEH’s current survival rate (two of five horses are alive) supports previously published survival rates of 10-25%.
